The diaminopyrimidine derivative or its pharmaceutically acceptable salt functions as a 5-HT 4  receptor agonist, and therefore can be usefully applied for preventing or treating dysfunction in gastrointestinal motility, one of the gastrointestinal diseases, such as gastroesophageal reflux disease (GERD), constipation, irritable bowel syndrome (IBS), dyspepsia, post-operative ileus, delayed gastric emptying, gastroparesis, intestinal pseudo-obstruction, drug-induced delayed transit, or diabetic gastric atony.

TECHNICAL FIELD

The present invention relates to a novel 5-HT₄ receptor agonist, morespecifically a novel diaminopyrimidine derivative or itspharmaceutically acceptable salt having an activity as a 5-HT₄ receptoragonist, a process for the preparation thereof, a pharmaceuticalcomposition comprising the same, and a use thereof.

BACKGROUND ART

Serotonin (5-hydroxytryptamine, 5-HT), one of the neurotransmitters, isbroadly distributed throughout human body including both the centralnervous system and the peripheral nervous system. Approximately 95% ofthe human body's total serotonin is found in the gastrointestinal tract,while about 5% thereof is found in the brain. Serotonin receptors arelocated in intestinal nerves, enterochromaffin cells, intestinal smoothmuscle, immune tissues, etc. Serotonin receptor subtypes include 5-HT₁,5-HT₂, 5-HT₃, 5-HT₄, 5-HT₅, 5-HT₆, and 5-HT₇. Interactions between thesevarious receptors and serotonin are linked to various physiologicalfunctions. Therefore, various researches have been performed fordeveloping therapeutic agents that are capable of interacting with aspecific serotonin subtype as a target. The researches includeidentification of 5-HT₄ receptors and active agents interactingtherewith (Langlois and Fischmeister, J. Med. Chem. 2003, 46, 319-344).

It has been found by the previous literatures that 5-HT₄ receptoragonists are useful for treating an abnormal gastrointestinal motility,i.e., dysfunction in gastrointestinal motility. The abnormalgastrointestinal motility may result in various disorders, for exampleirritable bowel syndrome (IBS), constipation, dyspepsia, delayed gastricemptying, gastroesophageal reflux disease (GERD), gastroparesis,post-operative ileus, intestinal pseudo-obstruction, drug-induceddelayed transit, etc.

Representative 5-HT₄ receptor agonists disclosed in prior arts includetegaserod (an aminoguanidine derivative, U.S. Pat. No. 5,510,353),prucalopride (a benzofuran carboxamide derivative, EP0445862), cisapride(a benzamide derivative, U.S. Pat. No. 4,962,115), mosapride(EP0243959), etc. These compounds are known as an agent stimulatinggastrointestinal motility.

Test Example 1 Evaluation of Agonistic Activity in CHO-K1 CellsExpressing Human 5-HT_(4(a))

As CHO-K1 cells stably expressing human 5-HT_(4(a)), we used theGeneBIAzer HTR4-CRE-bla CHO-K1 cells (Invitrogen Corp.). The cells werecultured, under the condition of 37° C. and 5% CO₂, in a DMEMsupplemented with 10% fetal bovine serum (FBS), 25 mM HEPES (pH7.4), 600μg/ml hygromycin B, 0.1 mM non-essential amino acids, 100 unit/mlpenicillin and 100 μg/ml streptomycin. Subcultures were performed threetimes per one week, each being at less than 80% confluence. At theprevious day before treating test compounds, the cells were collectedusing 0.5% trypsin/EDTA and then diluted with a DMEM supplemented with1% FBS, 25 mM HEPES, and 0.1 mM non-essential amino acids into 3.125×10⁵cells/ml. 32 μl of the diluted cells were added into 384-well plate (10⁴cells per well) and then incubated overnight. After the overnightculture, 8 μl of the medium having 1% of DMSO was added into thecell-free control well and the non-stimulating control well,respectively. 8 μl of the respective test compound dilutions (which hadbeen prepared by diluting by 100-times with the medium as mentioned inthe above) having 1% of DMSO were added to the respective remainingwells. After being cultured in the incubator for 5 hours, the wells ofthe 384-plate were treated with the substrate solution (8 μl per well)prepared according to the vendor's instruction (i.e., Invitrogen'sinstruction), and then incubated in the dark room for additional twohours. Agonistic activities on 5-HT₄ receptor were evaluated, on thebasis of fluorescence values of the cleavage-products by beta-lactamase.After exciting to 410 nm of wavelength using a fluorescence detector(Genios Pro), we measured the fluorescence values at two emissionwavelengths (first wavelength: 465 nm, second wavelength: 535 nm). Datawere analyzed on the basis of the ratio of fluorescence intensities ofeach well at the respective wavelengths. Each EC₅₀ value was calculatedby non-linear regression analysis using the “GraphPad Prism” program,based on the activities according to 8-different concentrations of thetest compounds. The results are shown in Table 2-1 and 2-2 below.
